This bill updates Michigan's water laws to streamline the registration process for large-scale water withdrawals while introducing new requirements for water conservation and reporting. It primarily affects property owners, agricultural operators, and industrial facilities that plan to extract significant amounts of water, requiring them to register their intended capacity before beginning operations. The legislation mandates that the state develop and post generic water conservation measures for different sectors, with specific rules for agriculture and data centers, and requires facilities permitted under new provisions to submit annual reports on wastewater usage and pollutant levels. Additionally, the bill clarifies exemptions for smaller residential wells and test wells, while establishing a timeline for property owners to develop their water capacity after registration or face invalidation of their application.
